WATER-F:LTER.`

SPECIFICATION'formi'ng part of Letters-Patent No. 283,103,ndated August 14, 1883.'

l Application fledMay 5,1883. (Nomodehj To all whom it may concern.-

Be it known that I, HENRY HARTMANN, of .IerseyLCity Heights, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Water- Filters, of which the following is a specifica'- tion. a I

This invention has reference to an improved device for filtering water for drinking purposes; and it consists'of anexterior vessel having water supply and discharge pipes, of an intermediate inverted vessel, and of an innermost cup, the latter ,being provided with a socalled lter-stone7 that is connected to the discharge-pipe. The intermediate spaces between the different vessels are filled withboneblack and charcoal, as will appear more fully hereinafter.

In the accompanying drawings, Figure 1` representsa side elevation, and Eig. 2 a vertical transverse section, `of Iny improved water-lter. Y

Similar letters of reference indicate correspending parts.

A represents an exterior vessel, of suitable cast metal, which is tightly closed by an inintermediate packing-ring and detachable lid, a A', that is screwed to a flange, a, at the upper end Vof the vesselA, by a numberof-fastening-` screws, b. The water-supply'pipe B` is connected by a suitable coupling7 d, to the lid A', and the water discharged from the same onto a corrugated disk, C, of compressed charcoal, which'is located immediately below the inletopening of the lidA, so as to distribute the water evenly in the upper'part of the vessel A."

At the interior of the exterior vessel, A, is arranged an inverted vessel, D, of `glass or othersuitable material, that rests loosely in the curved bottom of the vessel A, so that the water can pass between the bottom edge of the vessel `D andthe bottom of the vessel A. Within the inverted vessel D is arranged a second interior vesselor cup, E, also of glass,

at. the lower partoi the vessel A.

In the interior cup, E, is arranged a filteringstone, F, of burned carbonaceous clay or other composition, to which is` centrallyT applied the discharge-tube G, which passes through the -stopper E and the bottom of the vessel The space between the interior cup, E, andthe which is supported on astopper, E', located 45 edthrou gh the pulyerized charcoahth en passed through the vessel D in an upward direction,

then through the bone-black, and inally` through the porous filtering-stone F, being discharged through the pipe G to the outside.

The water is thoroughly purified and filtered in its passage through the iiltering device, not

only of impurities mechanically carried along, f

but also of impurities of a chemical nature.

The vessel A is supported on the wall by means of a bracket, e, of the iiange a, and by a laterally projecting heel, f, at the lower part of the vessel A, as shown in Fig.` `l.

Having thus described my invention, I claim as new and desire to secure by Letters Patentsel, A A', having supply-pipe B, an intermediate vessel, D, an interior cup, E, a filteringstone, F, in the cup E, and a discharge-pipe, G, applied centrally to said ltering-stone, the space `between thevessels being iilled with charcoal and bone-black, substantially as specii In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
